In this paper, we developed the lighting control system by location information and applied to operating workplace in our office for empirical study. The lighting control system is composed by the location information detection system, the LED lighting control system, and the favorite illuminance level data base. As a result of the application, the following conclusions were obtained. The location information can be gotten at narrow area by using semi-active tag and designing the low-frequency antenna in the office. The lighting control that uses adjusted lighting ratio database by illuminance level simulation is effective. The illuminance level of office worker's favor can be analised by the log which individual freely adjusted the illuminance level on the desk. Finally, we confirmed operation verification of the lighting control system by location information.
